Starting today, anyone who buys a new LG V30 will get $500 off a second V30, or get an LG V20 or LG G6 for completely free. Full retail price on the V30 is $800, so it isn’t quite a full get-one-free deal, more like a get-one-heavily-discounted. You also get a free LG G Pad X or G Pad X2 Plus with the deal, so in theory, you can buy one LG V30, and walk out with two smartphones and a tablet.

As ever with T-Mobile’s BOGO discounts, both new devices have to be on T-Mobile’s 24-month Equipment Installment Plan, and you have to add a new line of service for at least a month. Both of your smartphones will be charged at the usual EIP rate, which is $80 down and $30 a month for the V30, or $20 down and $20 a month for the LG G6. You get a $500 prepaid MasterCard as a rebate when you register your phone with T-Mobile.

Even if you don’t want the second device, using the promotion can get you a new LG V30 for $300, way below retail. Just sell the second device on Craigslist or eBay, take the prepaid MasterCard, and you’ll be left with 24 months of bill payments and about $1300 in cash.
